Front Panel Operation

Power Button

Press the Power button once to turn the Model 275 v.2 on. powered on the L and R indicators should illuminate green. Turn On Options switch is set to Audio or 12V.

Press it again to turn it off. When the unit is The Power button is inoperative when the

A and B Speaker Select Buttons

These buttons turn on the speaker pairs connected to the corresponding Speaker Pair A and B terminals. They will also select two single mono speakers connected to the corresponding Speaker Pair A and B terminals.

Note: The front panel buttons are inoperative when the Front Panel Speaker Selector switch is set to Lockout.

Protect Indicator

The Protect indicator will illuminate red and the unit will stop playing if the amp experiences an external fault condition. This prevents possible damage to the unit from continued operation. Examples of external fault conditions are short circuited speaker wires, excessive heat and trying to drive too many speakers at high levels.

If Protect illuminates you need to locate and correct the fault; for example, remove the short circuit, let the unit cool down, check the load impedance and the setting of the Speaker Load switch or lower the volume level. To reset the protection circuit you need to turn the unit off. If the amp is being turned on by a 12V trigger or audio sensing trigger then the easiest thing may be to simply unplug the unit from the AC outlet for about 10 seconds and then plug it back in.

Hi-Temp Indicator

Hi-Temp will illuminate red when the Model 275 v.2 exceeds its maximum safe operating temperature. If this happens the unit will activate its protection circuit and stop playing. It will remain in this protection mode until the temperature drops and the unit is turned off to reset its protection circuit. If Hi-Temp appears it’s likely the unit has been over-driven by too high a listening level or is attempting to drive a speaker load impedance that is too low. It’s also probable the unit has not been provided with sufficient ventilation. These conditions must be corrected before turning it on again to resume operation.

L and R Channel Status Indicators

L and R will illuminate green when the Model 275 v.2 power is on and it is operating normally. The L indicator will not light if a fault is only in the left channel; the R indicator will not light if a fault is only in the right channel. Neither L or R indicators will illuminate if there is a general fault or if the temperature is too high.
